The future of Supercars young gun Richie Stanaway is up in the air after he was sensationally stood down for the Gold Coast 600’s final race on Sunday for missing a fan autograph session.

Heavyweight Holden outfit Garry Rogers Motorsport (GRM) dropped the bombshell that Super2 Series driver Dylan O’Keeffe would replace Stanaway just before the first round of qualifying for Sunday’s 300km event.

GRM boss Garry Rogers gave no guarantees that Stanaway would return behind the wheel for the season’s final two rounds.

Stanaway’s fate will be decided when GRM bosses discuss his future next week.

In the meantime, Stanaway will remain in Rogers’ bad books.

“Discipline and respect are vital parts of your wellbeing in life, in my opinion,” Rogers said in a video statement.

“Today Richie failed to turn up at a signing session at the team merchandise area for all of the fans, both young and old, who were waiting to see him.

“For a professional, that’s just not good enough. We need to be accountable for our actions.

“Let me assure you, it’s been a tough decision but the fact is good manners and discipline never ever go out of fashion and let’s hope and pray a lot can be learnt from this.”

Stanaway was clearly devastated by the decision, saying he had not given up on the team despite GRM making the shock call earlier this month that they would pull out of Supercars racing at the end of 2019 after a stellar 24-year stint due to rising costs.

“It’s an isolated situation,” Stanaway said of his autograph session no show.

“I mean, given the circumstances obviously the team’s pulling out, it would have been easy for me to drop my focus or not pretend like I’m interested or whatever, but I feel like I’ve come here and put my best foot forward.

“I’ve been trying my best for the team and done everything I can, so it’s not like I’ve been doing other things that could give them a reason to do this.”

Stanaway’s dumping was so sudden that O’Keeffe had to borrow GRM co-driver Chris Pither’s race suit and helmet after being told just 20 minutes before Sunday’s opening qualifying session that he was competing.

GRM will bow out of Supercars in 2020, having claimed the 2000 Bathurst 1000 title and blooded some of the category’s biggest names including seven-time series champion Jamie Whincup and current championship leader Scott McLaughlin.
